Build a website with AI for free

Want to use sharepa straight from the chat? How to connect Claude or ChatGPT

Yes, you can build a website with AI for free, with the chat you already use. ChatGPT, Claude, Gemini and Perplexity all build a page on their free plans. What's usually missing for free is an address of its own. Below: what each chat can do, prompts that work, and how to put the page online for free.

What your chat does on the free plan

As of November 2026. We tested ChatGPT, Claude, Gemini and Perplexity ourselves; the others are based on what the providers say.

Chat	Builds a page	Shows a preview	Shares a link itself	Own address
ChatGPT	Yes	Yes, in the code block	No, ChatGPT Sites starts at Plus	No
Claude	Yes, as an artifact	Yes	Yes, with Share	No
Gemini	Yes, in Canvas	Yes	Yes, link on gemini.google.com	No
Perplexity	Yes	Yes, for files	Only in Computer trial runs	No
Mistral Le Chat	Yes, in Canvas	Yes	Yes, link to the mini app	No
Copilot	Yes	Only in a preview release	No	No
Grok	Yes	Yes, in Grok Studio	Only the chat	No
DeepSeek	Yes, as code	Unclear	No	No

sharepa gives a page from any of these chats its own address like name.sharepa.page, with a password if you want. Three pages are free. From ChatGPT and Claude you can skip copying with the connector.

How it works

Paste one of the prompts below into your chat and fill in the brackets.
Copy the code or download the file. How that works in each chat is on the pages linked in the table.
Paste or drop it at app.getsharepa.ch/neu, check the preview, pick an address, go live.

Prompts for common pages

Landing page for an offer

Write a landing page for [offer, e.g. maths tutoring for secondary school in Lucerne]. Sections: headline with the benefit, who it's for, how it works, price, questions, contact. One HTML file with the CSS inside, no React, system fonts, no scripts, fonts or images from other servers.

Invitation

Make an invitation for [occasion, e.g. Sandra's 40th birthday on 12 September at the boathouse in Thun] as an HTML page. Date, time, venue with address, programme, what to bring, RSVP deadline. Easy to read on a phone, no images from other websites.

Calculator

Build a calculator for [purpose, e.g. a flat's yearly heating costs in francs]: [inputs]. Show the result straight away, with a short explanation of the maths. One HTML file with CSS and JavaScript inside, no React, no external scripts.

Form that arrives in sharepa

Build a contact form for [purpose, e.g. garden maintenance requests in Aarau] with name, email, message and a checkbox for agreeing to the privacy policy. The form is <form action="/__sharepa/formular" method="post"> with a submit button type="submit". One HTML file, no React, no external scripts.

Nothing from other servers

Change the page so it loads nothing from other servers: no Google Fonts, no scripts from CDNs, no images by link. Use system fonts and your own styles in the style element. Output the whole file.

Tips for every chat

Ask for one file

Ask for a single HTML file with the CSS and JavaScript inside. Projects split over several files can't simply be pasted.

File or code block

In our tests, ChatGPT, Perplexity and Claude liked to create a downloadable file instead of writing the code into the chat. sharepa takes both: paste the code or drop the file.

Replace the placeholders

Chats fill gaps with examples: links to example.com, invented names, invented testimonials. Read the page in the preview before it goes live.

Keep working in the same chat

Make changes in the same chat and publish the new version to the same address. The link stays the same.

Legal notice

A business page in Switzerland, Germany or Austria needs provider details. Ask the chat to add a "Legal notice" section with yours.

Cookies and privacy

A page without tracking and without content from other servers usually needs no cookie banner. sharepa's analytics set no cookies. A form needs a short note on what happens to the data.

Chats do like to add things that load from other servers, though: Google Fonts, Tailwind from a CDN, images by link. Gemini did so in our test. With Google Fonts, every visit passes the visitor's IP address to Google; in Germany that led to a court ruling in 2022 and a wave of warning letters. The "Nothing from other servers" prompt above cleans that up.

What it costs

Chat: building pages is free in every chat listed. Publishing from the chat itself is free only in Claude, Gemini and Mistral, as a link on their site.
sharepa: three pages free, with password, analytics and one custom domain. More pages with the one-time plan.
Custom domain: from a registrar of your choice, usually 10 to 20 francs a year.

Questions

Can I really build a website with AI for free?

Yes. Every major chat gives you the code on its free plan, and sharepa puts three pages online for free.

Which AI is best for building a website?

In our test, code from ChatGPT, Claude, Gemini and Perplexity ran on sharepa without changes. Perplexity helps when the page needs current facts, because it searches the web first. Otherwise, use the chat you already know.

Do I need an account with the chat?

Perplexity worked without signing in. Artifacts in Claude and Canvas in Gemini need an account.

Is this a real website?

It's a single page at its own address. For a site with many subpages, a blog or a shop, a site builder fits better.
